When Morgan mated fruit flies with the genotypes XrYr (homozygous for recessive traits on X and Y chromosomes) and XrY (heterozygous for the X chromosome), he observed a 1:1 ratio of offspring. The offspring would consist of XrYr and XrY genotypes, leading to a mix of phenotypes that correspond to the traits associated with those alleles. This experiment helped elucidate the principles of sex-linked inheritance in fruit flies.

What was the result when Morgan mated a white eyed male fruit fly with a red eyed female fruited fly?
When Morgan mated a white-eyed male fruit fly with a red-eyed female fruit fly, the first generation offspring all had red eyes. In the next generation, because females would have the X chromosome for white eyes, about half the offspring would have white eyes. The offspring with white eyes were all male, meaning he discovered eye color in fruit flies showed a sex-linked trait. The result of this was a generation of red eyed and white eyed individuals. If the red eyed female was heterozygous, this is possible.
How are fruit flies born?
Fruit flies undergo a process called complete metamorphosis. They start as eggs laid by adult female fruit flies on fermenting fruit or organic matter. The eggs hatch into larvae (maggots) that feed and grow before pupating into adult fruit flies.
Which of the following best describes why the process of evolution is easier to study in fruit flies than in birds?
Because fruit flies have small cell counts Because the life cycle of a fruit fly is short enough to actually see a change in a short period of time. With larger animals, it could take many years to see an actual change. With fruit flies, you can see many generations of change in a shorter period of time.
Do fruit flies have a hard shell?
No. Fruit flies do not have hard shells. Fruit flies look like tiny semi transparent flies. A bug with a hard shell is probably some type of beetle. If you are having a problem with swarms of them in your kitchen it is probably some kind of stored food beetle such as: carpet beetles, cigarette beetles, drugstore beetles, or larder beetles.
Are fruit flies attracted to dog urine in carpet?
Yes, fruit flies can be attracted to dog urine, especially if it contains organic matter that can serve as a food source for them. The scent of urine can also attract other pests, which may then draw fruit flies to the area. If the urine is not cleaned properly, the residual odor and potential nutrients can create an ideal environment for fruit flies to thrive. Regular cleaning and proper sanitation are essential to prevent their attraction.
What was the result when Morgan mated fruit flies with the genotypes?
When Thomas Hunt Morgan mated fruit flies with specific genotypes, he observed deviations from the expected Mendelian ratios, indicating that certain traits were linked on the same chromosome. This led to the discovery of genetic linkage and the concept of gene mapping.
Which fruit flies did thomas hunt Morgan use?
thomas hunt morgan studied fruit flies. :)
Was Morgan the first to use fruit flies in genetics experiments?
yes
Why was Thomas Hunt Morgan important with fruit flies?
Thomas Hunt Morgan was important with fruit flies because he used them to establish the chromosome theory of inheritance, demonstrating that genes are located on chromosomes. His research with fruit flies provided key insights into how genes are inherited and laid the foundation for modern genetics.
Why were fruit flies useful in Morgan's research?
Fruit flies were useful in Morgan's research for several reasons. They have a short life cycle, making it easier to study multiple generations. They have a small genome that is easy to manipulate and study. They also exhibit a wide variety of genetic traits that can be easily observed and tracked.
Which organism did Thomas Hunt Morgan use to study gene mapping?
Fruit flies
Which scientist studied fruit flies?
The scientist that studied fruit flies was Thomas Hunt Morgan. He was born in 1855 and died at the age of 79 in 1945. He was an evolutionary biologist.
Why was Thomas Morgan's work with the fruit flies important?
Thomas Morgan's work with fruit flies was important because it helped establish the chromosomal theory of inheritance. By observing patterns of inheritance in fruit flies, Morgan was able to demonstrate the connection between genetic traits and specific chromosomes, laying the foundation for our understanding of genetics today. His work was crucial in advancing the field of genetics and providing insights into how traits are inherited.
Why was Thomas Morgan and work with fruit flies important?
He gave an understanding of how chromosomes effect heredity.
Why did Morgan choose fruit flies for his experiment?
Morgan chose fruit flies (Drosophila melanogaster) for his experiment because they have a short life cycle, produce many offspring, and have easily observable traits like eye color that follow simple patterns of inheritance. These characteristics made fruit flies a good model organism for studying genetics and understanding the principles of heredity.
What is a reason of Thomas Hunt Morgan's research with fruit flies?
Thomas Hunt Morgan used fruit flies because they have a short lifespan, produce many offspring, and have easily observable genetic traits. This enabled Morgan to study inheritance patterns and gene linkage, ultimately leading to the discovery of sex-linked inheritance.
What was first used in genetic studies by thomas Morgan in the early 1900s?
Plato users, Fruit flies.
